The NX Series’ optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Terrain doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Lexus NX Series are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The GMC Terrain doesn’t offer height-adjustable front seat belts.

The NX Series has standard Whiplash Injury Lessening Seats, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Seats system moves the headrests forward to prevent neck and spine injuries. The Terrain doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The NX Series offers an optional Intuitive Parking Assist with Automatic Braking that use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Terrain doesn’t offer backup collision prevention brakes.

The NX Series’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Terrain doesn’t offer a driver alert monitor.

Both the NX Series and the Terrain have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH, results indicate that the Lexus NX Series is safer than the GMC Terrain:

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the NX Series the rating of “Top Pick” for 2018, a rating granted to only 104 vehicles tested by the IIHS. The Terrain was a “Top Pick” for 2017, but no longer qualifies under the tighter 2018 guidelines.

It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Terrain’s suspension doesn’t offer adjustable shock absorbers.

The NX 300h handles at .80 G’s, while the Terrain Denali AWD pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The NX Series uses gas struts to support the hood for easier service access. The Terrain uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

J.D. Power and Associates surveys of service recipients show that Lexus service is better than GMC. J.D. Power ranks Lexus second in service department satisfaction. With a 41% lower rating, GMC is ranked 14th.

The NX Series’ front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Terrain’s passenger windows don’t close automatically.

If the windows are left open on the NX Series the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (Your Lexus service department must activate this window function.) The driver of the Terrain can only close the windows from inside the vehicle, with the ignition on.

The NX Series’ optional wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Terrain’s manually variable intermittent wipers have to be constantly adjusted.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The NX Series’ standard headlights were rated “Acceptable” by the IIHS, while the Terrain’s headlights are rated “Poor.”

To help drivers avoid possible obstacles, the NX Series F Sport has standard cornering lights to illuminate around corners when the turn signals are activated. The Terrain doesn’t offer cornering lights. The NX Series also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The NX Series has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Terrain and isn’t available on the Terrain SL.

The NX Series’ standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Terrain SL doesn’t offer automatic air conditioning.

The NX Series’ available GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Terrain’s available navigation system doesn’t offer real-time traffic updates.

Insurance will cost less for the NX Series owner. The Car Book by Jack Gillis rates the NX Series with a number “5” insurance rate while the Terrain is rated higher at a number “10” rate.

The NX Series will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the NX Series will retain 50.95% to 51.77% of its original price after five years, while the Terrain only retains 36.82% to 45.76%.

According to The Car Book by Jack Gillis, the NX Series is less expensive to operate than the Terrain because typical repairs cost much less on the NX Series than the Terrain, including $200 less for a muffler, $170 less for front brake pads, $244 less for a fuel pump and $260 less for a power steering pump.
